Winter operation Rubber seals and components In order to prevent the weather-strip-
ping from freezing, apply BMW rubber
treatment or silicone spray to the seals
on the doors, hood and liftgate/tailgate.
A full range of car care products is
available from your BMW center.< Snow chains Mount BMW snow chains
* only on tire
size 235/65 R 17. Always mount chains
in pairs and on the rear wheels only.
Read and comply with the chain manu-
facturer's safety precautions. Do not
exceed a maximum speed of 30 mph
(50 km/h).
Starting offWhen starting in deep snow or
"rocking" the vehicle free, it may be
advisable to deactivate the DSC system
briefly. Refer to page 94.
Driving on low-traction road
surfaces Use smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. Also shift
to the next lower gear at an early point
when approaching grades or slopes.
Maintain an adequate distance
between yourself and the car ahead. BrakingWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
The resulting increases in braking
distance are considerable and should
be kept in mind at all times.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response. If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake
pedal until the wheels just start to roll
again while still maintaining enough
force to continue braking. Following
that, increase pedal pressure again.
Reduce the pressure as the wheels
lock, then reapply pressure. Repeat this
braking sequence.
This type of staggered braking will
reduce the braking distance, and the
vehicle still remains responsive to
steering.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.
Do not shift down on slick road
surfaces if you want to decelerate.
Doing so could cause the wheels to
lose traction and skid, thus resulting in
the loss of vehicle control.<
Depress the clutch during hard
braking on road surfaces that
provide only poor or uneven traction.<

HoodTo unlock Pull the lever located under the left-
hand side of the instrument panel.
Do not work on your vehicle
without appropriate skills. Switch
off the engine and allow it to cool down
before working in the engine compart-
ment. Always disconnect the battery
before working on any electrical systems
or equipment, especially when these are
located within the engine compartment.
Comply with all applicable instructions
and warnings. Failure to work in an
informed, professional manner when
servicing components and materials
constitutes a safety hazard for vehicle
occupants and other road users. If you
are not familiar with the guidelines,
please have the operations performed
by your BMW center.< 530us093
To open Pull the release handle and open the
hood. 530us094
To close Allow the hood to fall from a height of
about 12 in (30 cm) so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, as with all closing
procedures
.
If it is determined that the hood is not
completely closed while driving, stop
immediately and close it securely.< 530us095

Engine oilChecking oil level1 Park the vehicle on a level surface.
2 Shut the engine off after it has
reached normal operating tempera-
ture.
3 After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material.
4 Push the dipstick carefully all the way
into the guide tube and pull it out
again.
5 The oil level should be in between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 530us100
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.530us205
Adding engine oilWait until the level has dropped to just
above the lower mark before adding oil.
However, do not wait until the oil level
drops below the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.< 530us101

Engine oilSpecified engine oils The quality of the engine oil selected
has critical significance for the opera-
tion and service life of an engine. Based
on extensive testing, BMW has
approved only certain engine oils.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Use only oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" which have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain
this information.
Viscosity ratingsViscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Engine oil
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Recommendation: have the oil changed
by your BMW center.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oils, grease and similar
materials so that they are inaccessible
to children. Comply with warning labels
and information on containers.<

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the factory specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene–glycol. For this
reason, do not spill antifreeze with
corrosion inhibitor on hot engine parts.
It could ignite and cause serious
burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold approx. +68 7(+20 6):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
end of the red float is aligned with the
upper edge of the filler opening (refer to
the arrow in the illustration), or max.
0.8 in (2 cm) higher, i. e. up to the mark
on the float (refer also to the schematic
diagramm, next to the cap).530us102
Adding coolant Wait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant temper-
aturegauge in the instrument cluster
must be located in the blue zone. If it is
not, there is a danger of scalding.
1 Start by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then
open the cap.
2 If the coolant is low, slowly add
coolant until the correct level is
reached — do not overfill.
The coolant is a mixture of water
and extended-duty antifreeze with
corrosion inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every four years.
